ROCHESTER — During tonight’s City Council meeting, a presentation will take place regarding the East Rochester School building.

After a space needs study completed in October 2011, the school district’s Building Committee is considering altering the school’s building. The study showed insufficient parking areas, inadequate classroom acoustics, and student pickup interfering with community traffic patterns.

Also during tonight’s meeting, the City Council will hear an update on the Great Bay Estuary Coalition’s efforts to prevent the Environmental Protection Agency from imposing the strictest limit on the amount of nitrogen that can be discharged from local communities’ wastewater treatment plants. While Rochester’s plant discharges more than 20 milligrams per liter of nitrogen, the EPA has indicated that an upcoming permit would limit that amount to 3 milligrams per liter, which would require the city to make multimillion dollar upgrades to its wastewater treatment plant.

Also, the Department of Public Works will update the council tonight on the Strafford Square capital improvement project, designs for which are currently under way.

Tonight’s meeting will begin with a public input session, and will end with a nonmeeting and a nonpublic meeting regarding land matters.

The meeting will take place at 7 p.m., in the council chambers at the City Hall.
